Kasich to back Biden?

According to the Associated Press, former Ohio governor and candidate for the presidential nomination John Kasich has been approached to speak at the Democratic National Convention, a slimmed-down and mostly online event in Milwaukee, Wisconsin next month.

Kasich is also a former congressman and committee chair, an influential Republican who would be quite a get to speak against a Republican president – but one with some views and parts of his record in government that Democrats, by and large, do not share.

Biden’s deputy campaign manager, Kate Bedingfield, would not confirm the approach to Kasich but she told the AP: “In terms of Republican supporters, I think it speaks to a career of being able to work across the aisle, of being able to actually get things done. We welcome the support of anybody who’d rather see Joe Biden be president than Donald Trump.”

Kasich, who ran for the Republican nomination in 2016 and ended up writing in John McCain as his choice for president, has been critical of Trump for some time. In 2018, he told the Guardian:

I’m not a Johnny-come-lately to this … most of the, people have been upset with him, and then endorse him and then they get upset with him. I just have not operated that way … I did not feel public pressure to have to go and support somebody that I was not convinced was going to pull the country together.
