Opinion polls and election forecasters favour Democrats to pick up the minimum of 23 seats they need on Tuesday to capture a majority in the U.S. House of Representatives, which would enable them to stymie Trump's legislative agenda and investigate his administration.
Yet it's that kind of middle-road tack that risks alienating Democrats who want nothing to do with Trump.
This was the year when a former one-term House member, Republican Abraham Lincoln, gained national prominence for his failed Senate bid against the incumbent Democrat, Stephen Douglas.
What should we expect from a Democratic House?
New Mexico also tipped into the Democratic column, with voters choosing Rep. Michelle Lujan Grisham to succeed two-term Republican Gov. Susana Martinez.
Nancy Pelosi, the House minority leader, said Trump's stunning upset two years ago ignited a call to action within the Democratic party. The GOP held a trifecta of power in 25 states, compared with just eight for Democrats.
"If you look back through the last 50 or 60 years of U.S. history, if you are an incumbent President, the chances are you will be re-elected and there is a strong pattern of the United States two terms for one party, two terms for the other".
But a win is not necessarily in the bag, he cautioned. "The rhetoric is meaningless to me", Mr. McKenna said.
And they appear particularly motivated to vote.
It also, however, almost closes the door on Democratic hopes to retake the Senate. "Because so long as they win Texas, Tennessee and North Dakota - and everyone thinks they're going to - they have 50 senators", O'Connell said. And only twice in the past eight decades has the president's party picked up House seats in the midterms. Republicans were largely on defense but also were angling for gains in a few traditionally Democratic states, such CT.
House losses in midterm elections, however, tend to be large. There are also 36 governor's contests that are poised to determine if Democrats can make gains at the state level and roll back a longstanding Republican advantage.
Many Democrats are counting on anti-Trump fervor to drive their base to the polls, but some advocate ignoring the politics of personal destruction and zeroing in on policy debates.
After the Civil War, the Democratic Party was identified as the party of the vanquished Confederacy, making it largely a regional party in the South.
Democrat Andrew Gillum, 39, the African American mayor of Tallahassee, is locked in an acrimonious battle with Ron DeSantis, 40, a member of the House of Representatives and ardent Trump supporter.
"(Democrats) will have subpoena power and the ability to get documents and testimony", West said on what could happen if Democrats win the House.
Such a scenario would represent a significant threat to the White House, since it would empower Democratic committee chairmen to subject the White House to unprecedented scrutiny on everything from Trump's tax returns and business dealings to scandal in government agencies.
Canada, the US and Mexico still have to ratify the United States-Mexico-Canada Agreement.
Many Trump supporters are working class males who see themselves as displaced by illegal migrants, at a time when blue collar jobs have gone overseas.
Trump also could face more pushback from Democrats on trade tariffs he has introduced, particularly in farm states hard hit by retaliatory measures from China or manufacturing states hit by higher steel and aluminium prices.
The past week has seen Trump make a number of stops in several USA states including Missouri.
The message people get, however, will be pretty focused, he said.
Most Democratic candidates in tight races stayed away from harsh criticism of Trump during the campaign's final stretch, focusing instead on bread-and-butter issues like keeping down healthcare costs, maintaining insurance protections for people with pre-existing medical conditions and safeguarding the Social Security retirement and Medicare healthcare programmes for senior citizens.
Galdieri said that Trump's campaign took off back in 2015 "because of the hard line he took on immigration - that led him to the GOP nomination and to a win in the electoral college".
"They still haven't accepted that they lost the election in 2016", he said. All of these topics theoretically have potential for bipartisan cooperation, although it remains to be seen whether that will actually come to fruition.
