Teflon Don confounds Democrats . Democrats have attacked the president every which way, but polling and focus groups show none of it's working.

Politico reports:

Democrats tried attacking Donald Trump as unfit for the presidency. They’ve made the case that he’s ineffective, pointing to his failure to sign a single major piece of legislation into law after eight months in the job. They’ve argued that Trump is using the presidency to enrich himself, and that his campaign was in cahoots with Russia.

None of it is working.

Data from a range of focus groups and internal polls in swing states paint a difficult picture for the Democratic Party heading into the 2018 midterms and 2020 presidential election. It suggests that Democrats are naive if they believe Trump’s historically low approval numbers mean a landslide is coming. The party is defending 10 Senate seats in states that Trump won and needs to flip 24 House seats to take control of that chamber.

The research, conducted by private firms and for Democratic campaign arms, is rarely made public but was described to POLITICO in interviews with a dozen top operatives who’ve been analyzing the results coming in.

“If that’s the attitude that’s driving the Democratic Party, we’re going to drive right into the ocean,” said Anson Kaye, a strategist at media firm GMMB who worked on the Obama and Clinton campaigns and is in conversations with potential clients for next year.

Worse news, they worry: Many of the ideas party leaders have latched on to in an attempt to appeal to their lost voters — free college tuition, raising the minimum wage to $15, even Medicaid for all — test poorly among voters outside the base. The people in these polls and focus groups tend to see those proposals as empty promises, at best.
