Distance from the Old Regime
Wanting to distance oneself from the former regime was also a big deal. The older politicians were trying to smooth things over into the post-Soviet system, but they themselves were part of the Communist power structure. Their success was also based on surviving Soviet bureaucracy and such, and was corrupt. They were rejected by new politicians, perhaps with the desire to move forward. The emerging right used this to get into power, opted for a more nationalistic program and public debate was re-shaped.
