An endorsement from President Obama can make a big difference in a Democratic primary race. That’s why Democratic Pennsylvania Senate candidate Katie McGinty is running a new ad proudly touting the President’s endorsement of her ahead of the April 26th primary. The narrator gets right to the point by starting, “President Obama endorses Katie McGinty for U.S. Senate.” The ad echoes the announcement McGinty made March 30 announcing endorsements from President Obama and Vice President Joe Biden. The ad quotes President Obama calling McGinty “a champion for working families.” It also claims “In Pennsylvania, McGinty helped implement Obamacare and expanded coverage for 500,000 people.” The ad features President Obama’s face and name onscreen nearly as often as McGinty’s – clearly trying to link the two in the minds of voters. Meanwhile, it also connects incumbent Republican Senator Pat Toomey to presidential frontrunner Donald Trump. Released the day after Trump made comments about wanting to “punish” women for having an abortion, the ad states, “Trump and Toomey have attacked women’s health care and Social Security.” The ad explicitly attempts to present McGinty as a counter to the Trump-Toomey agenda: “To fight back, President Obama wants McGinty in the Senate to protect Obamacare, Social Security, and for equal pay for women.” Already one of Republicans’ more vulnerable incumbent Senators, Toomey could be seriously hurt in the general election with Trump atop the ticket.
