Leaders for Liberty: Sen. Rand Paul and Rep. Justin Amash

The American Conservative’s Daniel McCarthy explains how liberty-minded Republicans, exemplified by Rand Paul and Justin Amash, represent “a qualitative change in tone and policy emphasis for the GOP, particularly on national security and foreign policy.” McCarthy also explains that the public “has shown to have no appetite for the decades-long wars that Tom Cotton’s [Arkansas’s newly elected senator] Republican Party appears to portend.”

But with Bush’s downfall came a need to redefine the Republican Party’s ideology and brand. After the country as a whole repudiated Bush by turning to Democrats in 2006 and 2008, the GOP also repudiated him by turning in 2010 to the Tea Party and a new brand of liberty-minded Republicans exemplified by Sen. Rand Paul and Rep. Justin Amash. These “liberty movement” Republicans were few in number but represented a qualitative change in tone and policy emphasis for the GOP, particularly on national security and foreign policy. One could easily imagine Republicans of this sort as the wave of the future, if the GOP were to have any future at all: these were the kind of Republicans who might represent a viable conservatism in an increasingly diverse country where marijuana is legal and same-sex marriage commands majority support. Their anti-authoritarianism and commitment to cultural federalism suggested a way forward for the party. Win or lose in years to come, they were certainly not the same Bush brand that voters had rejected in 2006, 2008, and indeed 2010.

Yet now Bush is ancient history, and the un-Bush of 2008, Barack Obama, has begun to exhibit distinctly shrublike characteristics—as Bruce Bartlett has shown, Obama is something between a moderate Republican of the old Rockefeller variety and a direct continuation of George W. Bush. The powerful but ill-defined anti-Bush “brand” that shaped both parties between 2006 and 2012 has given way to a Democratic Party that now defends the Bush-like policies it once defined itself against and a Republican Party that in opposing Obama does so for reasons unrelated to his resemblance to his predecessor. Republicans today can once again employ their familiar decades-old ideological armament against a militarily inept, big-spending, socially liberal Democrat. These weapons have done the trick for decades—until the Bush disaster deprived them of their effectiveness—so who needs new ideas?
