For the House in 1994, I doubt it. The Dems probably keep the House narrowly, the Contract with America is averted since Gingrich never has the platform to put it forth, Bill Clinton (and likewise Hillary Rodham, who goes right back to using her maiden name after the election) fades away, and people get sick of the GOP in the White House in 1996. Assuming whatever Democrat runs in '96 is victorious in 2000, the Iraq invasion is averted due to no Bush II presidency. However, the economic collapse devastates the Democrats in 2008, leading to John McCain getting elected (and probably re-elected.)
The circumstances that gave us Obama never happen, he ends up staying in the Senate, and really, beyond McCain, the deck is completely shuffled for both parties. The good news? Trump doesn't gain any traction and is regarded as the GOP equipment of a joke candidate.
