No Trump supporter has any right to extend any sympathy to her or her family after the crap your current leader (who you’ll dump as soon as it’s convenient, just like you did with Dubya) threw at the Bush family.
I don't think you will find too many people on the left who think W was an overtly good president. He doesn't seem quite as bad as he did around 2007-2008, mostly because of the ethnic nationalist turn the Republican party has since taken under Trump, but he still seems pretty awful.
Democrats today commonly express positive views of GWB because he is useful to them. Since Trump is currently the enemy, complimenting Bush bears no political consequences as he's not running for anything. It is useful for them to build a facade of bipartisan credibility, so GWB is a convenient prop. It also helps them find another angle to criticize Trump from since it doesn't matter much what direction Trump is criticized from as long as he's criticized. That's all. Politicos do that sort of thing all the time. Republicans did this with Hillary/Obama once upon a time too. Only a fool (which incidentally does include most of the GOP establishment 
) takes such compliments as genuine.
If you are talking about the elder Bush -- then you are talking about the source of the sane foreign policy that Bill Clinton maintained and Barack Obama restored. The younger Bush at the least left no question of where his loyalty lay and did not have a sleazy personal life. Gonald Trump is simply horrible.
