Newly minted U.S. Rep. Rob Bresnahan swore he wouldn’t support gutting government benefits such as Medicaid that residents of his northeastern Pennsylvania district rely on.

Then the first-term Republican voted for a bill that could do just that.

Bresnahan and two other Pennsylvania Republicans won in November by some of the smallest margins in all of Congress, prevailing in a critical battleground state that not only helped decide the presidency but also aided the GOP in taking control of the U.S. House.

Bresnahan, fellow newcomer Ryan Mackenzie and seven-term Rep. Scott Perry now find themselves navigating the delicate politics of a divided electorate once again, this time during the first weeks of President Donald Trump’s second term as he makes economy-altering decisions.
