While he probably has never been as bad as the Bushes, even I’m not sure how active he would be in his support—he turns 96 in two weeks.
I’m glad he supports Trump, but he’s no Trump, and Kansas is more in tune with what Dole was politically than it is with Trump. At best GOP as being content with defending the moral high ground while letting the Dems converting most of the country into moral low ground.
Despite a lot of Dole-bashing, he was the Conservative Senator from Kansas (a lifetime rating of 91% from the ACU). Consider his seatmate was the RINO Nancy Kassebaum (48% Conservative lifetime rating). Her predecessor, who also served with Dole, Jim Pearson, was even more execrable. A left-winger Republican who was closer to Ted Kennedy (he got a 16% Conservative rating in his last full year in office, 1978). So it definitely has been worse before in KS.
Besides, it’s not fair to compare any GOP politician to Trump. There’s only one of him. Dole was still a pretty tough guy early on in his time. It was unfortunate he ran too much a gentlemanly race in 1996 against the human debris Clintoons. The last genuine war hero to run for that office, too, and be nominated (sorry, Lurch).
