Ideally, the two parties set forth their respective visions, seeking to sway the undecided electorate with an appeal both to governing ideology and pragmatic economic impact. The country debates these weighty matters, carefully considering the trade offs and trying to determine which approach will best secure our economic prosperity (or at least, economic security) for the future.
Oh wait, I'm in a country where hardly anyone will even read the Ryan Budget, despite the fact that it is available online. Only a handful more will actually go to trusted sources (of any economic ideology) for analysis. No one will actually suggest that there are trade offs that need to be wieghed. Instead, everyone will insist that their vision has only benefits, whereas the very ideology of the opposition ensures that their vision will result in a dystopian future that consists either of a Socialist Collective in which religion is outlawed and "real Americans" (you know who you are, what color your skin is, and what your first language is -- no need to say it out loud) are enslaved to a faceless elite (you know who they are, you know what color their skin will be, and you know what their first language will be), or a Feudal Theocracy in which the wealthy elite (you know who they are, you know what their skin color and sex are, you know what their first language is) will hunt us for sport, make us fight in gladiatorial games for their amusement, subject us to concubinage -- then force us to bear their unwanted offspring because all forms of contraception are outlawed. Because, as everyone will assure us, the other side is evil, and has no redeeming virtues.
But that's OK, because the vast majority of the electorate won't even remember the Ryan Budget come election time. They are likely to vote on the basis of some random thing that makes them feel good or bad about the particular candidate as a person. Whether that's high oil prices, low oil prices, an anecdote about doggies, the fact that he uses a teleprompter, that he's too wooden, too elitist, too whatever. To the extent any of the people voting for Republicans don't like the Ryan budget, they will decide that they are "not serious" and this is just "political posturing" because, of course, no one would seriously do all the stuff Republicans are promising to do in the Ryan budget.
And then, if the Republicans win the Senate and the Presidency, and pass the Ryan budget, everyone will be like "whoa! I so totally did not see that coming!"
