Question: Whyyy didn’t Democrats repeal the debt limit when they had 60 Senators in 2009?

Answer: There exist figures closely involved in or exposed to financial markets whose favor and support is necessary to the institutional structure and continuation of the party as constituted since the collapse of labor unions who very strongly prefer that the amount of government debt issuance be held to caps known well in advance and requiring approval of some portion of the Republican Party even in periods of Democratic trifecta.
