For a politician, of any party, the chance of them having not committed crimes against humanity increases exponentially after two terms, and essentially reaches infinity at about 6.
Swalswell's indiscretions she habits were known about, both parties essentially let it slide because they all have skeletons. They're all embezzling millions. They all are abusing drugs, more and more controlled substances as the boomers that are just alcoholics pass away. They all are engaging in sex tourism, having sex with prostitutes the same age as Epstein abused, in counties where that are is legal(Canada was a hot spot for senators to go hook up with 16 year old in strip clubs across the border in the 90's. They all Weinstein their staff.
This is the average, there are absolutely those that are worse, age some exceptions to the rule that are probably relatively clean.
The only reason it's not an escalation between parties, is because it's politically convenient to remove Swallowswell, and the Republicans are informed on what the Dems are doing.
You think it's just a coincidence an even split of House members are resigning today over their sex scandals?
