The most highly placed elected Republican is House Speaker Mike Johnson. Today he is in New York to support Donald Trump at Trump's "banana republic" trial in Manhattan.
Politico makes fun of Johnson doing so, I view it differently. If you remember, Johnson also showed up at Columbia University during the protests there and spoke out against what was happening.
In both cases the Speaker, second in succession to the presidency and therefore the most senior elected Republican official in the land, is showing the flag. He is going where things are not as they should be and putting the GOP on record as opposing what is there being done.
As such, I believe his behavior is entirely on target. That doing so also strengthens his position as Speaker is, as Cajuns say in his native Louisiana, lagniappe - a bonus.
