try to use the loopholes/double-standards which Twitter/FB have created for political figures to try to bully them into letting her back on those platforms. We've seen numerous examples of social media accounts which exactly repost what a politician posts and the regular person gets suspended or deleted, not the politician. She's trying to exploit that basic unfairness.
As well as the general improvement in visibility when one runs for office, even in a tilting at windmills, going down in flames kind of way.
Her whole "thing" is being a right wing bigot who is persecuted for being a right wing bigot, so give her money so she can fight the powers that be. But in her desperation for enough continually new attention to keep that grift gravy train running, she overstepped and the big social media companies decided she wasn't a big enough deal to keep them from banning her. Now she's lost the major conduits she had used to get in front of people's eyeballs and thereby make a living off of being a professional jerk. So she needs a new method. Politics it is then.
