When you give in to hostage-taking, you set a pattern that just encourages people to take more hostages, and ask for bigger ransoms every time. This is exactly what is happening thanks to President Obama previously declaring that he must give in to Republican hostage taking tactics. From the Hill:
House Republicans are considering a plan to grant only incremental increases to the federal debt limit in a bid to extract more concessions on spending cuts and budgetary reform from the Obama administration.
The idea has a champion in Grover Norquist, the conservative activist and president of Americans for Tax Reform, who says he is “building allies” in the House Republican Conference to push for extending the debt limit every two months.
Since Obama allows and even encourages this kind of tactic, it is just going to keep happening and getting worse.
Even if Obama were trying to use the debt ceiling to play a game of rotating villain, so he could pretend he was “forced” into accepting some regressive deficit reduction package, in the long run, feigning weakness is a really bad idea.
