Electoral success for Republicans appears to be to fool people into believing things that aren’t true.
It’s been dismal under Republicans, especially if you look at the growth in underlying factors such as wages and jobs (and net growth from the housing bubble).
Personal liberty? Tapping phones, body searches at airports, etc., etc. under Republicans have decreased, not increased freedom and liberty. And that doesn’t even touch upon social issues where their authoritarian instincts also reduce freedom and liberty for some segments of the population.
Spending restraint? Look at the Bush years.
