MONONGAHELA, Pa. (AP) — The enthusiasm for Donald Trump’s unique brand of nationalist populism has cut into traditional Democratic strongholds in places such as Monongahela in western Pennsylvania. That’s where House Republicans recently outlined their election-year campaign agenda, called “Commitment to America.” They’re hoping they can tap into the same political sentiment Trump used to attract voters. But it’s not clear whether the support that propelled Trump to the White House will be there on Election Day this November. Just as challenging for the Republican Party is whether Trump’s false claims of voter fraud will hurt the GOP if voters decide to sit out the election.
