Newly tapped as counselor to the president, Kellyanne Conway told CNBC on Thursday that Democrats facing re-election will help pass tax reform.
"Bush was able to push through his tax relief package in June 2001 with the help of many Democratic U.S. senators, many of whom were up for election the following year in 2002," she said on "Squawk Box."
"We see a great analogy there to 2018," she argued, citing the 25 Democratic seats up for election in 2018, with 10 of them in states Trump won in the 2016 election. Only eight Republican seats are up in 2018.
"I have a feeling [Democrats] will make a list and check it twice to find out if they should be supporting this tax package," added Conway, who served as Trump campaign manager. "It's going to be very difficult for them to resist such major investments in the economy."
In announcing Conway's appointment, Trump said she "played a crucial role in my victory. She is a tireless and tenacious advocate of my agenda, and has amazing insights on how to effectively communicate our message."
Shortly after news of her planned appointment, Conway told CNBC: "Every time people bet against Donald Trump they are sorely disappointed."
She added that she thinks it's great to call the stock market's advance since Election Day the "Trump rally," citing her reasons behind the optimism. "They know there's energy coming, there's a corporate tax break coming, capital gains tax reductions coming," she said.
Conway, who turned down the job of press secretary, predicted an announcement for that position would come soon. "Many qualified men and women have put in for press secretary," she said. "I'm there to support the press secretary and the communications team as well."
