The GOP retains its power through heavily-gerrymandered congressional districts, and that corruption of the election process happened because of control of state-level professional politicians. It cannot be fixed. (When the authorities have all the tools, they make the rules.)
As the above poster points out - that stance completely ignores reality.
You cant gerrymander the senate and yet the right didn't just win there - the won huge.
How do you reconcile the astronomically unpopular ratings of the Republican Party with its success in elections?
This election was all about numbers . . . the Democratic Party stood for nothing, and only committed partisan Republicans (predictably) came to vote. About 20% of eligible voters put these people in office.
Because those numbers have no real connection to reality. How do you reconcile the fact that congress has an approval rating that is damn near single digits yet most are able to retain their seat? Easy - blaming the amorphous 'republicans' or 'democrats' of 'congress' is an easy cop out that requires almost no thought. Those very same people are just fine with THEIR congressman.
Opinion polls about what someone thinks of a single issue or a party are utterly irrelevant. What matters is what happens when they go to the polls and actually put a candidate in. What they think of the people they can actually vote for rather than a 'party' that does not actually exist on the ballot.
