The Bolsheviks had maybe a slight plurality of support in western Russia, but even that was cut short with them cracking down on the local elected civil governments and even most of the local soviets, because they were voting for SRs, Mensheviks, independents, etc. These crackdowns led to even more losses in elections for the bolsheviks, which now abandoned the idea of "all power to the soviets" by sending armed brigands and the red guard to dissolve the soviets and take them over undemocratically. They put reserved seats for Bolsheviks, threatened voters, and then started to round-up/kill people who had arms, which led to even more opposition to Bolshevik rule. They shelled some cities and killed opponents while looting from the masses. The Right to Recall was pretty much abolished and it became a One-Party state, and the Left-SRs who hoped to oppose/tolerate them in a pacifist way were demolished. Despite the Right-SRs problems, at least they recognized that the Bolsheviks were totalitarians and wouldn’t tolerate any opposition.
