But even though each party has a presence in each state, they are not competitive in each. Republicans dominate some states (like Texas) while Democrats dominate others (like California). There are only a handful of states where there is a close balance between the two - Florida and Ohio for example.
This author from the American Prospect thinks this is a problem and that democracy would be better served if each party was competitive in each of the fifty states. The roots of government dysfunction might be found in this lack of competition:
The real winner, if the parties started competing for votes across the map, wouldn’t be Republicans or Democrats; it would be small-d democracy. Voter turnout would surely rise. When only one party is courting them, voters disconnect. In 2012 battleground states, where both parties poured resources into voter outreach and engagement, turnout was high. In Ohio, 65 percent of the voting-eligible population cast a ballot; in Virginia, 66 percent did; and in Colorado, a whopping 70 percent turned out. But one-party states like Texas (50 percent) and California (55 percent) were both below the national average.
Voters can’t hold elected officials accountable if their party affiliation virtually assures their re-election. A weak opposition party can’t serve as an effective watchdog on those in power, either. Politicians in unchallenged parties also tend to move to ideological extremes. When general elections are largely decided in party primaries, as they are in Illinois and Texas, small numbers of highly motivated voters can carry the day; that’s how the Tea Party took over the Republican Party in states like Texas. It’s what elected Ted Cruz and what emboldened him to orchestrate an unpopular government shutdown without having to worry about his own political future. In the strange world that noncompetitive politics has wrought, Cruz is doing precisely what Republican primary voters back home elected him to do.
Neither party, of course, will pursue a 50-state strategy because it thinks such a plan is good for democracy. But we’re at a juncture when both believe they can benefit from talking to voters they’ve long ignored. If the parties embraced 50-state strategies, rather than putting most of their resources into a handful of battlegrounds like Ohio and Florida, who would gain the most by 2020 or 2030? It’s impossible to say. Democrats would win over a lot of people simply by giving them a reason to vote. Republicans might acquire even more converts by revising their message to appeal to Latinos and other voters who have written them off. One thing’s for sure, though: American politics would be a lot healthier.
