Left 4 Dead has a new VGUI voting system, it's controlled by a bunch of events. You can use either a string from the resource file, or L4D_TargetID_Player which will let you create any vote you want.

How voting works

Server begins by sending a vote_started event, followed by a vote_changed event. Client's use the "Vote" command to register their votes, after which the server sends a vote_cast_yes or vote_case_no event, along with a vote_changed event.

When the vote is complete, the server sends vote_ended, followed by either vote_passed or vote_failed.

Example voting plugin

This is a basic plugin that starts a vote, "Is gaben fat?". It does not ensure the same client does not vote multiple times, nor does it actually kick the user.

#include <sourcemod>
new yesvotes;
new novotes;
#define MAX_VOTES 4

public OnPluginStart()
{
	RegConsoleCmd("testvote",Callvote_Handler);
	RegConsoleCmd("Vote",vote);
}
public Action:Callvote_Handler(client, args)
{
	new Handle:msg = CreateEvent("vote_started");
	SetEventString(msg,"issue","#L4D_TargetID_Player");
	SetEventString(msg,"param1","Is gaben fat?");
	SetEventInt(msg,"team",0);
	SetEventInt(msg,"initiator",0);
	FireEvent(msg);
	
	yesvotes = 0;
	novotes = 0;
	UpdateVotes();
	
	return Plugin_Handled;
}
public UpdateVotes()
{
	new Handle:msg = CreateEvent("vote_changed");
	SetEventInt(msg,"yesVotes",yesvotes);
	SetEventInt(msg,"noVotes",novotes);
	SetEventInt(msg,"potentialVotes",MAX_VOTES);
	FireEvent(msg);
	
	if (yesvotes+novotes == MAX_VOTES)
	{
		PrintToServer("voting complete!");
		msg = CreateEvent("vote_ended");
		FireEvent(msg);
		if (yesvotes > novotes)
		{
			msg = CreateEvent("vote_passed");
			SetEventString(msg,"details","#L4D_TargetID_Player");
			SetEventString(msg,"param1","Gaben is fat");
			SetEventInt(msg,"team",0);
			FireEvent(msg);
		}
		else
		{
			msg = CreateEvent("vote_failed");
			SetEventInt(msg,"team",0);
			FireEvent(msg);
		}
	}
}
public Action:vote(client, args)
{
	new String:arg[8];
	GetCmdArg(1,arg,8);
	PrintToServer("Got vote %s from %i",arg,client);
	if (strcmp(arg,"Yes",true) == 0)
	{
		yesvotes++;
	}
	else if (strcmp(arg,"No",true) == 0)
	{
		novotes++;
	}
	
	UpdateVotes();
	return Plugin_Continue;
}
