Yeah, Trump sure did a lot of good with those SCOTUS picks, COVID, trade wars... Oh wait.
The Republicans never do anything good, so I'm not seeing why anyone would root for them. I mean, on its face, in a vacuum, that position would make sense but to anyone that has been paying attention to anything political over the last 50+ years will realize there is no reason to root for Republicans, unless you are an accelerationist, which is just dumb.
Honestly, even in a vacuum is doesn't make sense because parties in general are split between ideological lines, so in most cases, like a general election, you are voting against your political opposite. Why would you wish for your political opposite to have success in terms of legislation? It's funny because this sentiment of hoping for the president to do well is only ever pushed on liberals, conservatives hate every Democratic president and call for impeachment on all of them. This tolerance of the intolerable will be our downfall.
edit: I can understand hoping any president improves the economy, even though Republicans consistently screw our economy while campaigning on being responsible but there really should be no hope the Republicans do well, instead, you should hope their poor performance leads to losing seats in the next election cycle.
