Leading up to the debateRepublican senators on Capitol Hill sought to highlight Vice President Kamala Harris’s “flip-flopping” on policy over the years, a preview of attacks that former President Donald Trump intends to deploy in the debate against Harris on Tuesday.

“I think everybody around the country is asking the question who is the vice president and what does she actually stand for,” said Sen. John Thune (R-SD), the No. 2 Republican in the Senate. “After all, she’s only done one interview since she became the Democrat nominee, and she spent the last month trying to reverse herself on all the positions she previously held.”

“She has flip-flopped on confiscating guns, the electric vehicle mandate, expanding the Supreme Court, and heck, she’s even flip-flopped on plastic straws,” Thune added.

In recent weeks, former President Donald Trump and his campaign have also seized on shifts in Harris’s stances on fracking, healthcare, and immigration, going so far as to call her “the greatest flip-flopper” at a rally in Michigan.

“This is who she really is. These are unguarded moments when we have been able to see her in her past life, but we haven’t been able to see her like this because she’s had that one interview and she’s been in a bubble while she campaigns,” Sen. Shelley Moore Capito (R-WV) said while speaking to reporters on Tuesday.
