2016[edit]

See also: United States Senate election in Pennsylvania, 2016

The race for Pennsylvania's U.S. Senate seat was one of nine competitive battleground races in 2016 that helped Republicans keep control of the upper chamber after the November 8 general election. Incumbent Pat Toomey (R), who began serving in the Senate in 2011, defeated Katie McGinty (D), Edward Clifford III (L), and write-in candidate Everett Stern (I) in the general election.

Toomey managed to keep his race with McGinty close by running his campaign separately from President-elect Donald Trump and by withholding whom he would vote for on Election Day. Toomey told reporters, “You know, I’m not campaigning with Donald Trump. He’s running his campaign. I’m running mine.”^[5][6][7]

Hillary Clinton, who campaigned with McGinty in October, criticized Toomey for not rejecting Trump as his party’s nominee. She said to a crowd of supporters, “How much does he have to hear or to see? If he doesn’t have the courage to stand up against Donald Trump after all of this, then how will he stand up to special interests and powerful forces that are going to be trying to have their way in Washington?”^[7]

McGinty repeated the criticism, saying to supporters, "What more does Pat Toomey need to hear? You're fired, that's a good one!"^[8]

Toomey was confident that his strategy to keep his re-election bid separate from the presidential race would be successful. He said, “I am convinced that Pennsylvania voters are going to make a complete separation in their minds. … There’s a presidential race going on, quite obviously, lots of attention, lots of focus, everybody’s got their opinion about it, and then there’s a totally separate thing happening in the Senate race — an incumbent senator most people know and an opponent. Totally separate campaign and totally separate judgment.”^[7] Toomey stated on Election Day that he voted for Trump.^[9]
