If you’ve walked into a poker game and holding a Full House...having put $5,000 down on the table, your most significant risk here is that someone else at the table holds four of a kind or a Straight Flush. Most folks would continue to sit at the table and even double-down on the bet.
In this case, Pelosi was awaken from slumber and now realizes (maybe for the entire past three months) that McConnell actually holds a Straight Flush, and there is virtually no way to lessen the lost money situation.
Good analogy. So Pelosi has decided that the only way for her to get out of this mess is to never put her cards on the table ... even if it means getting someone to pull a fire alarm in the casino in the desperate hope that everyone flees and forgets about the poker game.
